JP6975589B2 - Indicator light - Google Patents

Description

The present invention relates to an indicator lamp that indicates the position of a transmitter attached to, for example, a fire hydrant box, a device storage box, or the like.

A commonly used indicator lamp is generally formed of a red glove in which the top of a cone is hemispherical, and is mounted so as to protrude from the mounting surface (for example, Patent Document 1). See FIGS. 1 and 12).
The reason why the indicator light is projected from the mounting surface is to improve the visibility from the side of the mounting surface, but on the other hand, there is a risk that the indicator light may be damaged by an object colliding from the side.

Therefore, the present applicant discloses in Patent Document 2 for the purpose of obtaining an indicator lamp having a low risk of damage due to an impact due to an external force such as an object hitting from the outside while ensuring visibility from all directions. The indicator light has been proposed.
The indicator lamp of Patent Document 2 has a transmitter accommodating portion in the center, and a light emitting display portion is provided in a ring shape so as to surround the outer periphery of the transmitter accommodating portion.

The light emitting display unit has an inclined surface that is inclined inward and inward, and the front surface of the transmitter is located at the position on the innermost side of the inclined surface.
The inclined surface is positioned in front of the front of the transmitter so that the indicator light is not obstructed by the transmitter when viewed from the diagonal side. This is to satisfy the requirement of the law that "the indicator light is a red light and it can be easily identified that it is lit from a distance of 10 m along a direction at an angle of 15 degrees or more with the mounting surface". ..
